2. Reduce the friction coefficient. It can be achieved through various channels, such as surface treatment, improving the surface quality of the rail joint bar or adding some form of intermediary to the material contact surface.
3. Reduce contact pressure. There are many factors that affect the contact pressure. Reducing the contact pressure can effectively reduce the strength of the interaction force between the steel rail and the rail joint bar. Working conditions, axle load, vehicle speed, etc. will have a greater impact on it, some of which must be borne under working conditions, such as load, vehicle speed, etc., and some can be adjusted by improving working conditions, such as maintaining proper Rail seams, good joint maintenance, etc. In addition, the shape of the mating surface of the steel rail and the rail joint bar will also affect the contact pressure.
Due to the limited time, the method of extending the service life of the rail joint bar is here. I hope that everyone can pay attention to this problem, in addition to avoiding frequent problems with the rail joint bar, and at the same time, the railway switch can maintain a normal driving state for a long time. Of course, Kingrail Parts is a railway fasteners factory. Our company can not only provide you with more information about rail joint bars, but also recommend and provide you with reliable quality and various types of rail joint bars.
